Andy Murray got off to an easy start at the US Open in his attempt to become the fourth man in the Open era to reach all four Grand Slam finals in a single season.

The 2012 champion at Flushing Meadows and seeded No. 2 this year, Murray beat Lukas Rosol 6-3, 6-2, 6-2 on Tuesday night to get to the second round.

Murray lost to No. 1 Novak Djokovic in the finals of the Australian Open in January and French Open in June, and then won his second Wimbledon title last month.

Only Djokovic (last season), Roger Federer (2004, 2006 and 2007) and Rod Laver (1969, when he completed a calendar-year Grand Slam) have been to a season’s four major title matches since the professional era began in 1968.

Murray has won 23 of his past 24 matches, including an unprecedented second consecutive Olympic singles gold medal at the Rio Games this month.
